CABLE GRlP.

SPECIFICATION forming part of Letters Patent No. 448,035, dated March 10, 1891.

Application filed September 3, 1889. Serial No. 322,841. (No model.)

To all whom it may concern:

Be it known that I, CLEMENT HAZARD, a citizen of the United States, residing in the city and county of San Francisco, and State of California, have invented a new and useful Improvement in Cable-Grips, of which the following is a specification.

This invention relates to that class of cablegrips which are operated through a narrow slot or groove connecting with the channel or tunnel in which the cable travels below and between the rails.

The object of my invention is to render the grip more durable and provide a construction whereby the parts most liable to wear out or break may be readily replaced without discarding the parts which are still in good condition.

Figure 1 is a side elevation; Fig. 2, an end or edge view; Fig. 3, a perspective view of the main upper cross-bar; Fig. 4, a side elevation showing a reverse view of that shown in Fig. 1; Fig. 5, a lower cross-bar.

Referring by letter to the said drawings, A indicates an upper transverse strengtheningplate of my improved grip-frame, which is connected at its ends to the upper ends of the vertical side stiles D, which are connected at their lower ends to the vertical branches of a lower main cross-bar F and rest upon a shoulder 0 formed therein. This lower crossbar F is substantially of the form illustrated in Fig. 5, being provided with the vertical branches at its ends for attachment to the side stiles D and with the apertures d adjacent to its lower corners to receive the journals of the friction-pulleys over which the cable travels.

E indicates the upper horizontal cross-bar, which is connected at its ends to the upper ends of the stiles D 6n the side of the frame opposite to the cross-bar A. This cross-bar E, which is of the form shown, is provided with two integral cap-plates adjacent to its ends, which take over the ends of the stiles and may be attached thereto to afford additional strength to the frame.

The cross-bar E and the cross-barA are provided at aligned points with journal-apertures f to receive the fulcrum of an ordinary perspective view of the.

cable-grip lever, which is of the ordinaryconstruction and need not be further described in this specification.

The movable plate B, to which the upper cable-gripping die is attached, has its upper end attached in the usual or any approved manner to the ordinary operating-lever H and the depending bale C, connected to said lever.

The lower end of the movable connectingplate B is re-enforced on one of its sides by a transverse plate I, and to this plate I, I attach a transverse keeper-bar G, the ends of which extend over the vertical branches of the lower cross-bar F and serve to prevent a displacement of the plate B;

On' the side of the plate B opposite to the strengthening-plate I and adjacent to the lower end of said plate B, I attach a re-enforcing transverse strip N, the reduced ends of which extend over the side stiles of the frame and serve, in conjunction with the bar G on the opposite side of the frame, to pre vent a displacement of the connecting-plate. The lower edge of this transverse strip N is cut away, as better illustrated in Fig. 4, and is provided at its ends with depending branches 9, between which the upper cable-gripping die I). is secured to the said strip N by means of bolts or the like. This die I) is provided in its lower edge with the ordinary channelgroove to adapt it to better grasp the cable. The lower stationary die J is also provided on its upper edge with a channel-groove, and depending from the lower edge of said die is a branch P, which is slotted vertically, as at M, to receive an adjusting-screw L, and by the provision of the slotted depending branch it will be seen that the lower die J may be adjusted vertically with respect to the frictionpulleys a and the upper movable die.

L indicates platform-lugs which extend out from the cross-bar F and are provided with a vertical screw-threaded opening to receive bolts K, upon the upper ends of which the respective ends of the lower cable-die rest.

From the foregoing description it will be seen that I have provided a cable-grip comprising several distinctparts, which are so arranged and connected as to adord great strength and allow one part to be taken out and replaced without inconvenience. It will also be seen that by the construction described the strength of the grip is greatly increased and the danger of it breakingdown is obviated to a great extent.

Having described my invention, what I claim is 1. In acable-grip, substantially as described, the combination, with the main frame comprising the vertical side stiles and the upper and lower horizontal Crossbars, the lower substantially as described, for raising and lowering the said movable plate and its cablegripping die, substantially as specified.

2. The combination, with a movable plate vertically adjustable in a frame, substantially as described, and having a horizontal cablegripping die at its lower end, of the lower cable-gripping die having the depending vertically-slottedbranch, the adjusting-screw taking through the vertical slot in the said depending branch to fasten the same upon one of the lower horizontal bars of the frame, and the platformdugs attached to said bar of the frame and having" vertical screw-threaded apertures, and the screws or bolts taking through said apertures and bearing upon the lower sides of the adjustable die adjacent to the ends thereof, all adapted to operate substantially as specified.

CLEMENT HAZARD.
